Re: Traffic Shaping
I dont know the contracts ntl have regarding their peering but there is some flaws to the shaping rules mrben mentioned if they accurate and I understand it right.
If the peering is on the basis that equal traffic is going both directions and ntl start shaping only outbound traffic that could breach the contract.
If ntl pay fully for the peering and as such any traffic going over it is probably at ntl's discretion and they can shape as they please.
If the shaping is only for traffic from ntl to other isps presumably meaning upload traffic this will have no affect to the current downstream congestion which is clear on their network.
Also all the isps that I know of that use shaping are shaping downstream traffic so I just cant believe this is true, I think they will shape on type of traffic regardless of which way its going and the only traffic that will probably remain truly unshaped is VOIP services charged for by ntl themselves and traffic that an external isp may have paid ntl a premium for to have it unshaped (an example maybe bbc pay ntl to have their imp prioritised.)
